Ray-Ban RB4640 Authentic Prescription Sunglasses

What’s Right for You?

Single vision lenses have one consistent prescription strength across the entire lens. Choosing the correct type depends on your specific vision needs, whether you are short-sighted (myopia) or long-sighted (hyperopia).

• Best for seeing faraway objects, everyday tasks, and general wear
• Ideal for short-sighted (myopic) individuals who struggle with distance vision
• If your prescription does not include a reading addition (ADD value), these lenses may also work for some close-up or arm’s-length tasks.

• Best for arm’s-length tasks like computer work, cooking, and crafting
• Designed for specific intermediate vision needs, such as screen use
• Not suitable for distance vision—ensure this aligns with your daily activities

• Best for close-up tasks like reading books, doing paperwork, and detailed work
• Perfect for long-sighted (hyperopic) individuals who struggle with near vision
• It is not suitable for distance or intermediate vision – double-check that this option matches your needs

If you’re unsure which option is best for you, check your prescription or contact us for advice before ordering.
